have you tried a conditional default? you could create a route-map similarly
to the way you generate a conditional default into ospf...there is an
example on page 401 of Halabis second edition....
route-map Send-Default_if permit 10
match ip address 1 <permit 0.0.0.0 and parent isp peering network
match ip next-hop 2 <associate with parent isp bgp network
that way if your not getting the default you wont send another....
Good luck,
Felice

If your ISP will not originate default route, then point your default
network to your ISP's network as close as possible to the NAP. That way
problems within the ISP's network can easily be detected, and a backup route
can be used.
